C, Fig. 2, represents a lever pivoted in a bracket c, secured to hanger B and provided at its lower end with a handle c. The lower portion of the lever works in an elongated metal loop c2, secured to hanger B. On the outside of this loop there is secured a fiat spring c3, having a hook c4 at its free end, and in the spring and extending through and across the loop is a pin c5, which locks the lever C forward, thereby holding the section of lazy-tongs which is pivoted to it in a contracted position. A thumb-lever c, provided on its under side with a spring c7, (which rests on the handle,) is pivoted at cs, and its upper end engages with hook c, whereby when the lower end of said lever is pressed down the pin c5 will be withdrawn from loop c2, releasing lever C.

To the upper end of lever C there is attached one end of a wire C, the other end of which is attached to the upper end of a lever C2, which is pivoted in a bracket e, secured to hanger B. To this lever C2, near its lower end, is connected one end of a spiral spring cm, its other end being secured to hanger B.

D D represent two sections of lazy-tongs, one at each end of the track-wire A. These are constructed in the same manner as the usual form of lazy-tongs, except that where the levers cross in the middle I employ, instead of the usual straight fulcrum, a short bolt d,having a trunnion d on each end, and place a washer d2 on each trunnion outside of the levers to give a greater bearing for the trunnion, and then rivet the latter down into the washer, so that the levers fulcrum on the trunnions, and are thereby prevented from buckling. The bolts d are perforated horizontally, and the track-wire is passed through these perforations, as clearly seen in Fig. 7.

In order to clamp the rear ends of each section of lazy-tongs to the track-wire, as is necessary, I form the trunnions d on one end of a rod Z3 about three inches in length, having an enlargement d4 at its other end, which enlargement tapers rearwardly, is screw-threaded, and is kerted, as at d5, and on this screwthreaded portion I pass a nut d6. The trackwire passes through t-his rod, and as the nut is screwed on the kerfed portions grasp the.

wire, all as seen in Fig. 6.

In order to prevent the carrier from strik ing the front levers of the lazy-tongs, I provide a buffer l), which consists of a forwardly-proj ecting perforated metal rod, on the rear end of which the trunnions are formed, as above explained, and on the front end I secure a rubber tip b', as seen in Fig. 5. The outer end levers of section D of the lazy-tongs pass through slotst' in hanger B and are pivoted to lever C, as seen in Fig. 2, and the outer end levers of section D are each pivoted to ashort link (Z7, which is pivotally connected to a short arm (ZS, rigidly secured to lever C2, as seen in Fig. 4, one of the levers of the lazy-tongs passing through a slot t" in hanger B', as seen clearly in Fig. 10.

As seen in Fig. 4, section D of lazy-tongs is held in contracted position and released from that position as follows: As lever C2 closes in the lazy-tongs, a latch R pivoted to a bracket R, secured to hanger B, engages with a pin fr on the lazy-tongs, the inclined. front end of the latch riding up on the pin against the stress of a spiral spring r, secured to the latch and the bracket in a well-known manner. The latch R has a vertical arm r2 at its rear end,which arm carries at its upper end a laterally-projecting pin r3, with which a latch R2, pivoted at its rear end to lever C2, engages to rock latch R upward, so as to disengage it from pin r and releasethe lazytongs. At the time latch'R2 is in engagement with latch R a notch r4 in the under side of the former is over a laterally-projecting pin T5, secured in the bracket. From this construction it results that as the lazy-tongs are being contracted latch R engages with them, and latch R2 engages with latch R as seen in Fig. 10, and when lever C2 is moved, so as to expand the lazy-ton gs, latch R2 will rock and release latch R', and at the same time it will be raised so as to release its own hold as its notch is drawn back from over pin T5, when the parts will be in' the positions shown in Fig. 4.

Each section of lazy-tongs D and D is provided at its inner or forward end with a pair.

of jaws D2 for holding the carrier while at the sub-station or main station. Each pair of jaws consists of two bell-crank levers dg, pivoted to the inner sides ot' the lazy-tongs at d10, the rear arm of each jaw resting loosely in a holder du, formed of a strip of thin metal bentinward at a right angle at each end and riveted to the lazy-tongs, as seen in Figs'. l, lO, and 17. A thin flat spring dl2 is riveted at its rear end to one of the inward projections of the holder, its free end resting under the rear arm of the jaw in order to permit the jaws to yield and open when the knob on the carrier comes into contact with them, the jaws being normally closed, while the lazy-tongs are contracted. The carrierE is a rectangular box having a standard e at each end, to which is riveted a tubular runner e,'having enlargements e2 near each end, on which to secure lugs es, in which the wheels e4 are mounted, the upper sides of the enlargements c2 being cut out, as at e5, to permit the wheels to rest on the track-wire, as seen in Figs. S and 9. On each end of this runner there is a disk-like knob e6, rounded on its outer side, as shown.

The box is divided into two compartments eT and e8 by a partition e9, and has ahalf-bottom cw to close only one compartment at a time. Along each side of the box at the bottom is secured a cleat e, and on these cleats IOO IIO

the bottom e10,whose side'edges are enlarged other. On the under side of the bottom, at one end and on each side, there is an ear @12, in which is secured one end of a coil-spring cl3, the other end being secured in an ear e on the opposite side of the box. As thus constructed it will be readily understood that the bottom will be held normally under the compartment nearest the points of fastening of the springs to the box, and in order to hold it under the other compartment against the stress of the springs, I employ a catch @15, which is a thin strip of metal sliding vertically in keepers el, secured centrally on one side of the partition, the lower end of the catch entering a slot @17in the end of the bottom. To the upper end of the catch is secured a laterally-extending pin els, which passes through a hole in one end of a lever @19, said lever being fulcrumed in an ear 620, depending from the runner, the outer end of said lever having a downward slope, in rear of which there is a notch @21, for a purpose which will hereinafter appear. rlhe inner end of the lever is held down and the catch in engagement with a slot in the bottom bya coilspring e222, secured to the end of the lever and the top of the partition, as shown in Figs. 8 and 9. On tipping the lever the catch willbe disengaged from the bottom, and the latter' will be drawn over to the other compartment. A short stem 623, secured to thebottom, serves as a linger-hold for drawing and setting the bottom under the other compartment.

Vhile a cash-carrier apparatus is an essential element of my improved store-service, and while I have shown and described one system of apparatus well adapted for use as a part of the store-service, it is to be understood that I do not limit myself to the employ- `ment of any particular system of cash-carrier apparatus, as there are other systems aside from the one herein described, which, by slight mechanical changes, can be readily combined with the changeanaker, and therefore any such combination would be clearly within the scope of my invention. v

I will now proceed to describe the changemaker and other mechanisms connected therewith, which, together with a cash-carrier apparatus, compose my complete store-service.

F represents the skeleton frame-work of the change-maker, which when used in connection with the cash-carrier apparatus herein described may, for convenience, be clamped, as at d, to hanger B on one side and to a corresponding hanger B2 on the opposite side. It may, however, be otherwise supported at the desired elevation.

At each sub-station (see Figs. l, 2, and 3) there is a boxing G, secured to the hanger B and extending from a short distance below the wire A to near the ceiling of the room, slots h being cut in the boxing in register with the slots in the hanger, through which pass the end levers of the lazy-tongs, as shown. In the lower end of this boxing, which is made wide for the purpose, is located a key-board -Work F, as clearly shown in Fig. ll.

H, in which there is aseries of keys H', these keys bearing figures on their faces, indicating given amounts of money, ranging from live cents to ten dollars, in a manner Well understood. These keys pass through slots h in the boxing, and arepivoted at their rear ends in the key-board, as at h2.

As the keys H must be operated to throw up their corresponding indicator-tablets and push out the change after the carrier has left the sub-station, it is desirable when several pieces of money are Wanted at one time to be able to depress the desired number of keys simultaneously. For4 this purpose I pivot a bail II2 on the rod, on which the keys are pivoted, and attach links h3 to it at proper intervals to engage with hooks h4, secured in the under side of the keys, the bail being provided with a suitable hand-hold h5. By thus connecting the bail to the desired keys the latter may all be operated at once by pulling down on the bail.

To each of the keys II is connected one end of a wire l, whose other end is connected to one arm of a bell-crank 2, pivoted in a bracket Z, secured to the hanger B near the ceiling, there being one bell-crank foreach wire, the boxing serving as a housing for these wires. To the other arm of each of the bell cranks 2 is attached one end of a wire 4t, which leads to the main station, where itis attached to another bell-crank 5, pivoted in a bracket 6, secured to hanger B. These wires are housed in a metal tube I, supported at its ends by brackets '7and 8, secured to the hangers B and B', respectively. The ends of this tube are flared outward to receive the wires as they radiate from the bell-cranks, and in each vflared portion there is a perforated disk 9 through each perforatiomin which passes one of the Wires 4. The wire C', connecting levers C and C2, also passes through the disks. By means of these perforated disks the wires are prevented from sagging andbuckling. Vires I0 lead from bell-cranks 5 to another series ot' bell-cranks l1, pivoted vertically in standards j at one end of a shelf J, secured to brackets f, attached'to the rear side of frame- On this shelf there is another series of bell-cranks l2,

lpivoted horizontally a short distance apart,

and a wire 13 connects therear arm of each of these bell-cranks with the lower arm of each of the bell-cranks Il.

To the front arm of each of the horizontal bell-cranks l2 is pivoted one end of a forwardly-extending arm K, whose forward end is slotted, as at 14..

L represents a series of levers, each fulerumed near its center in lugs l5 on top of a cross-piece a2, which runs transversely of the frame-work F, and is slotted at regular intervals, as at l0, to permit the passage therethrough of said levers, the lower end of each of which also passes through the `slot l5 in each arm K, and is held in engagement with the arm by means of a pin 17 passed through IOO ITO

Vthe lever. Each lever L is held normally against a stop 18, which isa light strip of Wood extending across the frame F, by a spiral springlfhattached to the lever above its fulcrum and to a cross-piecer a3 on the rear side of the frame. A Wire loop 2O is attached to the upper end of each of these levers, for a purpose Which will presently appear.

To the upper end of each lever L is pivoted one end of a rod L', the other end of which is\pivoted to the rear end of a metal coin-slide L2, perforated at 21. The slides are of varying thicknesses, ranging from the thickness of four silver dollars down to that of a ten-cent piece, and the perforation 21. in

each slide is of a size to receive the piece or" pieces of money it is designed to take from its respective money-tube. Each of these slides Works in a recess 22 cut in the upper face of a slide-support L3, which issimply a plank secured in and extending across the frame near its front side, the depth of the recess being just equal to the thickness of the slide.

M represents a moneytube support, Which is secured squarely on top ofthe slide-support. It consists of a Wooden plank perforated at intervals, as at 23, for the reception of a sel ries of metal or glass tubes M', the perforations 23 registering with the perforations in slides L2. Each tube is designed to contain pieces of money of a denomination corresponding to that marked on the key that operates the slide beneath it. y

NrepresentsWhatltermthechange-guide, Whose function is to direct the pieces of money into the proper chute for delivery thence to the carrier belonging to any particular substation. It consists of an oblong box divided vertically by partitions n into as many compartments n as there are sub-stations in communication With the main station, four such compartments being shown in the present instance. ln each compartment therev is an inclined partition n2 extending from each end at the top to the bottom, these partitions converging in such manner as to leave an opening n3 of the size of the upper end of the chute WV, as clearly shown in Fig. let. The said chute may be of Wood or metal, and of any construction adapted to deliver the money into the carrier.

vN represents an inclined apron extending from the top edge of the rear Wall of the change-guide to the slide-support L3, to the front face of which it is secured, the upper suitable material, hinged to the top edge of one of the vertical partitions n in the changeguide N. The upper edge of the leaf rests normally against the recessedA portion n4 "of apron N', inorder that it may offer no obstruction to the money as the latter slides down the apron. The function of this leaf is when thrown back into vertical position to prevent the money falling down the apron from going beyond the iirst compartment of the change-guide, and when lying in its normal position While the money-changer is being operated from a second sub-station to serve as a prolongation of the apron'and'direct the money into the second compartment, the second leaf, which is shown in dotted lines in Fig. 12 and in' full lines in Fig.20, meanwhile serving to prevent the money from going bcyond the second compartment for which it is intended, and so on, it being understood that there is to be a leaf for each compartment, each operating independently of the others, as hereinafter described and as illustrated in 20. The leaves overlap each other at their upper edges, and as the apron may be made of any thickness it may be recessed sufficiently to permit the upper edges of all the leaves to lie in said recess.

O represents What I term the detainer, which holds on the apron N the money selected as change by the salesman until the cash-carrier reaches the main station. It consists ofv a thin board hinged at its upper edge at-24 to the under edge of a cross-piece f on the front side of the frame F, the lower edge of the detainer resting against the apron at a point above Where the leaves come into contact with it, as seen in Fig. 12, and a light spring 25 holds the detainer normally in contact with the apron.

26 represents wires secured at their lower ends in the upper edge of the cross-piece f of the frame,'and at their upper ends in an other similar cross-piece f 2, each pair of Wires serving as guides for an indicator-tablet O', of metal or other suitable material, bearing on its face a iigure or iigures indicative of a money value equal to that expressed on one of the keys. As clearly seen in Fig. 15, the tablet is provided on its rear side With two transverse metal strips 27, having loops 28 at their ends, Which pass over the Wires and hold the tablet. At the upper end of the tablet on the rearside is secured a laterallyextending Wire bail 2 9, and also on the rear side there is a light strip 'of spring metal, secured at its upper end to the tablet and carrying a forwardly-extending pin 30 at its lowerend, which pin passes through a perforation in the tablet.

To the upper edge of a face-platef3, secured to the cross-piece f of the frame, is hinged, as at 3l, a narrow strip O2, of Wood or metal, which serves as a support for the tablets When in their raised position, the spring-pins on the tablets resting on the upper edge of the support, which is caused to normally press against the tablets by a spring 32, attached to one of the postsof the frame and bearing against the front side of the support, this latter spring being considerably stronger than lof those carrying the pins on the indicatortablets.

P represents a series of right-angularlybent rock-arms, pivoted on a rod 33, extending transversely of the frame and secured in a beam fL at each side, the rock-arms being kept the required distance apart on the rod by spools 34E. The lower end of the rear f or vertical portion of each of these rockit (2, 5,11, and l2) will be rocked on its pivot in such manner as to cause the upper end of the lever L to be thrown forward, thus pushing the slide L2 forward until its perforation 2l has passed entirelybeyond the slide support, when the coin that was in the slide will fall onto the apron N and lodge against the detainer O. The same movement of lever L will also rock the rock-arm P in a manner to elevate its respective indicator-tablet O until the spring-pin 30 on the tablet has passed above the tablet-support O2, when the pin will be projected forward and rest on the upper edge of said support, it being understood that the pin SO normally extends through the tablet, as seen in Fig. l5; but in the ascent of the latter it is forced back until Hush with the front face of the tablet by contact with the inclined tablet-support, the spring` holding the latter being sufficiently strong to overcome the pressure by the pin 30. The full and dotted lines in Fig. 12 clearly indicate the above-described operations. The indicator-support is thrown forward to permit the indicator-tablets to drop by means of an arm P', whose front end rests normally against it, as clearly seen in Fig. 16. The rear end of this arm is pivoted to one arm of a bell-crank 35, pi voted on a block 36 on top of one of the beams A spiral spring 37, secured to the other arm of the bell-crank and to one of the rear posts of the frame, tends to hold the arm P in its normal position, the bell-crank being rocked to throw said arm P forward, and thus push the indicator-support forward by means of lever C2, that arm of the bell-crank to which the spring is attached being connected with said lever by means of a wire or cord 38, which passes over a pulley 39, mounted on the post of the frame, as seen in Fig. 10. The front end of arm P passes through and is supported by a keeper 40 on the inner side of one of the front posts of the frame, the keeper allowing vertical play of the arm. In the under side Y of the arm there is a notch 4l, having a square shoulder at the front and an incline at the rear. When arm I is in its normal position, this notched part rests on a pin 42, secured in the post, so that when the upper end of lever C2 is thrown rearward the bellcrank will be rocked to throw arm Il forward, pressing the indicator-support forward and allowing the tablet or tablets to drop. The arm P is raised as the notched portion passes over the pin until, when the notch has passed beyond the pin, the indicator-support is free to resume its normal position, as seen in Fig. IG, when the spiral spring 37 will rock the bell-crank in the opposite direction and Withdraw arm P as soon as the cord 38 is slackcned by the forward movement of the upper end of lever C2.

In order to prevent manipulation of the money-changer by an unauthorized person, I apply a lock Q 'to the bell-cranks 5, so arranged as to prevent any of the slides L2 from being operated while the cash-carrier E is at its sub-station. This lock consists of a rectangular metal plate hinged at its upper edge on a rod 43, mounted in the outer upwardlyturned arms of the brackets 6, in which the bell-cranks 5 are pivoted. A spiral spring 44, attached to the inner side of the lock and also to the rod ou which the bell-cranks are pivoted, serves to hold the lock normally over the lower arms of the bell-cranks, and a wire 45, attached to the lock and to lever C2, serves to withdraw the lock from engagement with the bell-cranks whenever the upper end of said lever is thrown outward, as seen in Figs. 1, 10, and 20. It will thus be seen that the money-changer remains inoperative until the carrier has been sent forward.

I will now describe the mechanism operated by the carrier E. The` bracket R, se,- cured to hanger B', as before stated, is provided on its outer Vside with two perforated ears 4:6, through which passes a slide-bar V S, which is held in forward position b y a spiral spring 47, attached to the front ear and to the bar. In the under side of the bar there is anotch 4S, (best seen in Fig. 10,) which is engaged by a pin 49, carried in the` vertical bifurcated branch of a right-angular arm 50, which straddles the bar. To the horizontal branch of said arm 50 is pivoted the lower arm of a bell-crank 5l, pivoted to a vertical extension 52 of bracket R. Arm 50` is held so that its pin 49 will engage with the notch in the slide-bar by means of a spiral spring 53, secured to it and to the upper arm of the bell-crank. A crescent-shaped lug 54 is secured on the side of bracket R in the path of arm 50 as it is carried backward by the slidebar, and a stud 55 in the bracket limits the movement of the bell-crank, so that on its return movement arml 50 will be causedto stop in the right place to engage the notch in the slide-bar. A vertical rod T reciproeates freely through a keeper 56, secured to the outer side of beam f4 of frame F, the lower .endl of said rod being pivoted to bellcrank 51. Y A small IOO l said beam.

' guide N.

Pn extends laterally from the rod above the keeper and enters the slotted end of one arm of a bell-crank 58, pivoted to the side of To the other arm of bell-crank S is pivoted one end of a rod T, the otherend of which islpivoted to a crank-arm 59, which is a right-angular extension of the rod on which the leaf N2is hinged to the change- The upper end of rod T strikes against the under` side of an outwardly'- extending flange 60 on one arm of a bellcrank G1, pivoted on the side of beam f5 of the frame. To the other arm of this bellcrank is pivoted one end of a rod T2., on the outerend of which are secured three set-nuts 62 63 64;. The inner nut G2, when the rod is moved forward, rides up on vthe rear end of a v latch t and depresses it, thus raising the front end,which engages with a metal strip or catch t on the end of the detainer O, to hold the detainer against the apron. The second nut (53 abuts against the inner side of catch t to push the detainer outward, and the third nut 64 is for the purpose of pulling the detainer back to its place against the apron.

Vhen cash-carrier apparatuses are connected with the money-changer on both sides, as will be explained farther on, there must be some provision for releasing the catches at each end of the detainer O simultaneously, and for this purpose I pivot two rods t2 t3 to the front side of the detainer, which rods are arranged in the form of acompound lever. The rod twhich is pivoted at 65, is enlarged and bifurcated at its inner end, as at 66, and the inner end of rod t3 plays in this bifurcation, said rod being pivoted at 67. The outer end of eaeh rod extends outward a short distance beyond the frame and engages in a slot 90, cut in eachlatch t, it being understood that in this case there is to be a catch at each side of the frame.

U represents the cash-receptacle, which is designed to receive the money deposited by the carrier, it being` suitably supported under the track-wire. As seen in Figs. 18 and 19, it is a rectangular box, having` a hopper it in its top, which is secured therein in any suitable manner. To one side of the hopper on its under edge is hinged a flap u, adapted when in its raised position to cover the opening into the box. The rod 68, on which the flap is hinged, extends a short distance outside the box at one end, and to it is rigidly secured at an obtuse angle one end of a short arm G9, the other end of said arm being pivoted to a rod 70. On a line with the lower edge of the hopper, Opposite the side on which the flap is hinged, there is a partition-plate 71, extending downward nearly half the depth of the box, and from the lower edge of this partition-plate back to the rear wall of the box the sides are slotted, as at 72.

Inside the main box there is a sliding box u2, (clearly shown in Fig. 19%) open at the front, side, and bottomvhichmoves back and fort-11, on Aways 73, secured to the sides of the Y main box just below the slots 72, the rear end wall of the sliding box being grooved, as at 74, to tit on the ways, the sides of the box extending only7 up to the lower edges of these grooves. Secured to the front ends of two arms 75, passed through openings 76 in thc rear wall of the sliding box, the other ends oi' said arms being secured tol the rear wall of the main box, is another partition-plate 77, which stands in line with partition-plate 71. The sliding box u2 is provided with a forwardlyextended apron 7S, secured in the front edges of its end walls near the bottom.

The front wall of the main box down to a line even with the lower edge of partition-v plate 77 is composed of a glass plate 79.

The sliding box is drawn rearward by means of the lever C2, to the lower end of which is attached one end of a short spiral spring SO, to whose other end is attached a cord 8l., which passes under a small pulley 82 in the rear wall of the main box and is secured to the rear wall of the sliding box. A spiral spring 83, attached to the lower edge of the rear wall of the sliding box and to the front wall of the main box, serves to move said box in the opposite direction. u is raised and lowered by means of the rod 7-0, whose lower end is bent at a right angle, enters the slot 72 in. its side of the main box, and is connected to the upper edge of the rear wall of the sliding box, the other end of the rod 70 being connected as before described.

I have as yet described my improved storeservice as embracing but a single cash-carrier apparatus. I will now explain how a number of these apparatuses lnay beconnected with the money-changer, each oneiof them independent of the other, there being an apparatus for each sub-station. Fig. 20 illustrates this feature so plainly that but little description is necessary, as the construction involves but aduplication of parts, with one or two minor exceptions, the first of which is that instead of having a hanger B for each cash-carrier apparatus I secure a column B3to the hanger, preferably by means of pipe-joints, as shown, an'd attach to it the working' parts attached to the hanger in the iirst instance. In the second place, instead of attaching rod T directly to the bell-crank 5l, I pivot it to the inner forwardly-extendin g end of a rock-arm V, journaled on the front sides of the hanger and column, and pivotV the outer forwardly-extending end of the rock-arm to the upper end of a short link 84, whose lower end is pivoted to the bell-crank 51, as shown in' Fig. 20, in which figure the bracket R and the parts which it carries (shown in the other figures as attached to the hanger) have been omitted for the purpose of clear illustration of this attachment of a second cash-carrier apparatus. As seen in Fig. 20, the wires 10 of all the-cash-carrier apparatuses are connected to the bell-cranks 1l on shelf J. When a key at any of the sub.-

operate the particular bell-crank 11 with which it is connected, all the other wires 10 connected with that bell-crank will. slack, as is evident. A third cash-carrier apparatus may be connected with the change-maker alongside the second, and so on, and also cash-carrier apparatuses may be attached to the change-maker on the opposite sidein the same manner.

I will now describe the operation of my store-service complete. The money-tubes are lirst filled with coins of a denomination corresponding to their respective keys. Those of the tubes, however, whose slides are capable of receiving four silver dollars (and all the slides whose respective keys are of greater value than two dollars are of just that capacity) are charged with small metal boxes X, like that shown in Fig. 21, whose lid is flush with the periphery of the body and fits snugly. In these boxes are placed paper money, each box containing money of the value of the tube in which it is placed. XVe will now suppose the salesman at his sub-station wishes thirty-ve cents change out of a dollar and that certain of the indicator-tablets are up, indicating the amount of change taken at a previous opcration. He rst places the dollar (if of paper, inclosed in one of the boxes X) in the compartment e8 of the carrier, and then releases lever C and draws it backward, when spring c10 will draw the `lower end of leverl C2 forward, and thereby throw its upper end outward. In this outward movement of the upper end of the lever bell-crank 35, through cord 38, will be rocked, so as to pushbar P forward to push the indicator'support back and allow the tablet-s to fall. In moving forward the inclined notch 41 in the bar rides up on pin 42, thereby raising the front end of the bar above the support, when the spring bearing against the latter will return it to its place. The outward movement of lever C causes the section D of the lazy-tongs to expand, and as they do so their jaws automatically release their hold on the carrier, which latter is given sufficient momentum by the lazy-tongs to send it to themain station. So soon as the carrier has been started on its way the salesman depresses the keys marked 10 and 25, when, through the instrumentality of their respective wires l 410 12 and the bellecranks with which they are connected, arms K will be moved rearward, thus drawing the lower ends of levers L in the same direction. rlhis movement of levers L causes the coin-slides L2 under the respective tubes containing the ten and twenty-live cent pieces to be pushed forward by the rods L until their perforations (the perforation in each slide containing a coin) have passed clear of the slide-support L3, when the coins will fall down onto apron l and rest against detainer O. At the same time the rock-arms P, connected with these particular levers L, will be so operated as to carry upward the indicatortablets marked 10 and 25, and when they have been fully elevated their spring-pins 30 willV fly forward and rest on top of the indicatorsupport, as before explained, holdingthe tablets elevated until another amount is to be indicated. As soon as pressure is off the keys, the springs 19 will draw levers L back to their normal position against stop 18, (whichinsnresthe perforation in each coin-slide resting1 directly under its 1noneytube,) thereby causing the keys to be raised and also lowering the rockarms P away from their in dicator-tablets in position for the bails on the tablets to fall over their upturned ends. Just before the knob e6 on the carrier E comes into contact with the jaws of lazy-tongs D at the main station the forward end of lever ew on the carrier strikes a downwardly-bent pin (Z13 on the forward end of the lazy-tongs, thereby causing thatY end of said lever to be slightly depressed and raising catch e1r out of engagement with the carrier-bottom, when tlie latt-er will immediately fly under the compartment e7, dropping the contents of compartment es into the cash-receptacle U. As soon as the notch @21 in the forward end of the carrier-lever has reached the pin d, the spiral spring 622 will draw down the inner end of that lever and force the catch e15 again in engagement with the bottom, holding it under compartment e7. As the rounded face of the knob on the carrier comes into contact with the jaws on theV lazytongs, the latter are forced open until the knob has entered, when the springs under their rear ends will cause them to close and hold the carrier in position with its compartment eT directly under the chute WV. lin entering the jaws the knob strikes against the end of the slide-bar S, which projects slightly beyond the buffer b on the lazy-tongs and pushes it rearward, the buffer preventing shock on the lazy-tongs. As the bar S slides backward, the arm 50 (by reason of its pin 49 being in engagement with notch 48 in' the under side of the bar) is also moved backward, thereby rocking bell-crank 51 and raising rod T. As said arm 50 moves under the lug 54, it is thereby depressed, disengaging pin 49 from the notch 48 in the slidebar, when the spring 47 will reset said bar in its forward position, allowing rod T and parts operated thereby to assume their normal positions. The raising of the rod T operates, through bell-crank 58 and rod T, to throw the leaf N2 up into a vertical position, and it also operates, through bell-crank 6l and rod T2, to throw the detainer O outward away from the apron N, the movement of the leaf being timed slightly ahead of that of the detainer. As the detainer leaves the apron, the money will slide down into the change-guide N, and thence through chute XV to the carrier. The salesman now pushes lever C forthe sub-station.

of the lower end of lever C2 the sliding boX u2 in the cash-receptacle U is drawn rearward and the money deposited by the carrier, which has meanwhile lain on top of said box, is scraped oft by partition-plate 7l onto apron 78, which by this time is in position to receive it, where it lies exposed to view until the lever C2 is again reversed, when it will be scraped oft theV apron by the glass front and fall into the bottom portion of the receptacle, which is locked.

rlhe operation of the duplicated mechanism is the-same as that already described.
